ACL based RP assignment
The rp-address command allows multiple static RP configurations. For each static RP, an ACL can
be given as an option to define the multicast address ranges that the static RP permit or deny to
serve.
A static RP by default serves the range of ff00::/8. if the RP is configured without an ACL name. If
an ACL name is given but the ACL is not defined, the static RP is set to inactive mode and it will not
cover any multicast group ranges.
The optional static RP ACL can be configured as a standard ACL or as an extended ACL. For an
extended ACL, the destination filter will be used to derive the multicast group range and all other
filters are ignored. The content of the ACL needs to be defined in the order of prefix length; the
longest prefix must be placed at the top of the ACL definition.
If there are overlapping group ranges among the static RPs, the static RP with the longest prefix
match will be selected. If more than one static RP covers the exact same group range, the highest
IP static RP will be used.
Configuration considerations
• The Static RP has higher precedence over RP learnt from the BSR.
• There is a limit of 32 static RPs in the systems.
Configuring an ACL based RP assignment
To configure an ACL based RP assignment; enter commands such as the following.
BigIron RX(config)# ipv6 router pim
BigIron RX(config-ipv6-pim-router)# rp-address 2000::16 acl1
Syntax: rp-address <ipv6_address> [<acl_name_or_id>]
Use the ipv6 address parameter to specify the IPv6 address of the router you want to designate as
an RP router.
Use the acl name or id (optional) parameter to specify the name or ID of the ACL that specifies
which multicast groups use this RP.
Displaying the static RP
Use the show ipv6 pim rp-set command to display static RP and the associated group ranges.
Syntax: show ipv6 pim rp-set
Use the show ipv6 pim rp-map command to display all current multicast group addresses to RP
address mapping.
BigIron RX(config)# show ipv6 pim rp-set
Number of group-to-RP mappings: 2
